A moist, low-pressure weather system over the Atlantic ocean collided with a cold air mass sitting over western Europe on January 7 and 8, 2021, resulting in heavy rainfall and flash floods in southern parts of Spain, and the heaviest snowfall in central, northern, and eastern parts of the country since 1971. The storm -- named Filomena by Spain's Meteorological Agency (AEMET) -- left hundreds of roads impassable and at least 3 people dead.
Capital Madrid was engulfed with rare, widespread accumulations between 20 and 30 cm (8 to 12 inches) on Friday, January 8, resulting in severe traffic disruption. Some areas in central, northern, and eastern Spain recorded up to 50 cm (20 inches) of snow.
Nearly 700 roads and highways were impassable across the country, forcing thousands of people to spend the night in their vehicles and prompting rescue operations for a number of drivers suffering the early onset of hypothermia.
In total, more than 2 500 trapped drivers were rescued by emergency workers.
Madrid Barajas International Airport had all incoming and outgoing flights suspended, leaving hundreds of passengers waiting for the weather to clear up.
